摘要
白钨矿型 CdMoO4 纳米粉是通过在 500 °C 的静态空气中煅烧草酸盐前驱体 2 小时制备的。草酸盐前驱体通过傅立叶变换红外光谱(FTIR)和热重分析(TGA)进行分析。拉曼光谱(RS)、X 射线衍射(XRD)、扫描电子显微镜(SEM)和能量色散 X 射线光谱(EDX)对合成的钼酸镉进行了表征。在过氧化氢存在下,通过亚甲基蓝(MB)染料的氧化反应测试了其催化活性。结果表明,CdMoO4 纳米粉体具有极高的催化活性,在 pH 值为 11 的碱性条件下,2 小时内的产率高达 98%。
A new approach to the preparation of CdMoO4 nanopowders with methylene blue oxidation activity evaluation
The scheelite-type CdMoO4 nanopowders were prepared through calcination of an oxalate precursor in static air at 500 °C for 2h. The oxalate precursor was analyzed by Fourier transform infrared spectroscopy (FTIR) and thermal gravimetric analysis (TGA). The as-synthesized cadmium molybdate was characterized by Raman spectroscopy (RS), X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive X-ray spectroscopy (EDX). Its catalytic activity was tested by the oxidation reaction of methylene blue (MB) dye in the presence of hydrogen peroxide. The obtained results showed that CdMoO4 nanopowders have very high catalytic activity with a yield of 98 % during a period of 2h under alkaline conditions at pH 11.
